Good 21-round mag for tx 22 - ProMag Polymer Taurus TX .22 LR 21-Round Pistol Magazine

Bought this to add another magazine and test performance. In my TX22, the 16 round mag runs without a problem, but the 22 round OEM magazine seems to have a lot of issues. So far, this 21 round mag has performed better than the OEM 22 round, and only 1 round less capacity. I've also bought the Tandemkross Green Springs for the 22 round mag and will test that out soon, but for now, this 21 round mag is a nice addition with fewer problems.
